For fun (IN IRELAND), there is the practice of ordering a whiskey to sip while the stout is being poured. The trick is to order another stout before you’re too close to the bottom of the present one so that you don’t go thirsty during the transition. If you forget, then you might have to order another whiskey while they pour the stout. After a few whiskeys, the stout tastes like mother’s milk and brand of either isn’t terribly important, although it just so happened that I witnessed this alcoholic caper committed with Bushmill’s whiskey and Guinness.
